MICHAEL J. GIBBONS, OF DAYTON, OHIO.

SANITARY PLUMBING.

SPECIFICATION forming part of Letters Patent No. 544,035,dated August 6, 1 895.

Application nea February 14, 1895. serai 110,538,351. (No modem l To all whom it may concern.-

Be it known that I, MICHAEL J. GIBBoNs, of Dayton, county of Montgomery, State of Ohio, have invented a new and useful'lmprovement in Sanitary Plumbing; and I do declare the following to be a full, clear, and exact description of the invention, such vas will enable others skilled in the art to which it appertains to make and use the same, retllocal ventilation, overfiows from Iixtures through safe waste-pipes, showing leakage at kitchen-sink.

The object of the'inv-entio'n is to provide means for ascertaining at any time the condition ot' the waste-pipes-that is, for detecting any leakage that may occur in or outside of the fixtures.

A further object is to combine in one system of plumbing means for obtaining local ventilation, a safe waste, and overliow from the xtures.

To these ends the invention consists of a system of plumbing having means conveniently located for testing the same, means for local ventilation consisting of a communication between the warm-air iiue and the main safe waste-pipe, and vent'rand overflow pipes connected with said safe waste-pipe and with the water-closet, wash-bowl, and bath-tub, all of whichwill be fully described in the following specificatiomtaken in connection withl the annexed drawings,which clearly illustrate my improvements.

The drawing presents a partly-sectional elevation of .a system of plumbing in accordance with my invention.

Referring in detail thereto, A designates the sewer or soil pipe, at'the lower end of which, and at a point where said pipe enters the building, I locate a cut-oft or valve B at any suitable point, and at the highest point of said soil-pipe a vwater-gage C is located,

substantially'as shown in the drawing, where lit will bc noted said water-gage is placed at a point above the vent and waste pipes.

I designates a Y-tting connected with the soil-pipe A, and tol which is connected a .waste-pipe 2 from the water-closet B' and a waste-pipe 3 with which waste-pipes 4 and 5 from the'wash-bowl C and the bath-tub D are connected. The waste-pipes 4 and 5 have traps 6 and 7, in which are placed ball-valves 8 and 9. 10 and 11 are vent-pipes for the waste-traps 6 and 7, and connect with a ventpipe 12, which in turn connects with the-upf per part of the'sewer or soil pipe A.

14 and 15 designate overow and local vent pipes from the water-closet, wash-bowl, and bath-tub, respectively, to a main safe waste and local vent pipe 16, which has safe wasteinlets ct and b below the wash-bowl and bathtub.

29 designates a' receptacle or saiing which is placed under the lentire system of plumbing and piping with which and the pipe 16 a pipe 30 connects. This pipe 16 discharges into the kitchen-sink E and is provided at its lower end with a valve 17, that normally closes said end.

18 designates a local ventilation-pipe which is connected with the safe 'waste-pipe 16 and enters the upper portion of the warm-air flue 19, preferably the kitchen-flue. (Shown in broken lines.)

v 20 is an overiiow-pipe from the kitchen-sink toa sink in the cellar (not shown) or elsewhere. l i

2l is a Waste-pipe from the kitchen-sink E to a grease-trap F, between which and the soilpipe A a waste-trap 22 is placed. 23 is a ballvalve having a seat in said trap, and 24 is a pipe from the upper portion of the soil-pipe A, venting said trap 2v2.V f 4 25 designates an inlet-pipe connected to the upper part of the pipe A at any convenient point and through which water from a tank` or city. supply may be-turned into said pipe A. The pipe 25 has a regulating-cock 26.

From the `foregoing description it Will be understood thatthe sub-system consisting of the safe waste and local vent pipe 16, and the auxiliary waste and vent pipes connected therewith constitute a system of themselves of safe waste and local ventilation pipes,which is one feature of my invention. The other feature resides in the means for testing the Waste and vent pipes, as hereinbefore described, without being put to the necessity of disconnecting any of the tixturcs. This test may be conveniently made at any time vby closing the valve B in the soil-pipe A and turning on the water in the inlet-pipe 25 until it registersat the gage C. This will indicate that the entire system of waste-fixtures to the points where the ball-valves 8, 9, and 23 are seated, and the trap vent-pipes connecting with said iixturesare filled with water.

'The outlets to the waste-pipes for testing purposes are closed by the pressure of the water upon the upper part of the bal1-valves. The water-closet is provided with a stop-cock 27, which is operated by a hand-lever 28 to close the waste-pipe 2. The waste and trapvent pipes having thus been filled with water through the inlet-pipe 25 and the soil-pipe A,

any leakage in the fixtures will be manifested pipe, provided with a valve or cut oit at a by the appearance of water at the kitchensink through the main safe waste-pipe 1G.

It will be noted that the ball-valves 8, 9, and 28 drop into their seats by gravity. Any back-pressure exerted upon them will cause said valves to tit more closely into their seats; therefore the possibility of sewer-gas escaping into the premises by backing through the waste-traps is avoided.`

Another useful feature of my improved system of sanitary plumbing is in the means afforded for preventing the entry of sewer-gas into the fixtures during such time as the house may be unoccupied. In such event the cutoff valve B may be closed, all the fixtures having previously been drained of water.

Having fully described my invention, l claim and'desire to secure by Letters Patentl. In sanitary plumbing, the combination of the overfiow and local ventilation pipe l6-, safety connections between said pipe and the bath tub and washstand, separate overflow and local ventilation pipes -13-, 14- and -15 between the closet, wash-stand and bath tub, respectively, and said pipe -16-, and a pipe communicating with the latter pipe and with a warm air line, whereby means are provided for obtaining local Ventilation, and an outlet for the overflow and leakage from the fixtures through said pipe -1 G-substantiall y as shown and described.

2. In sanitary plumbing, the combination of the safety waste and local vent pipe (16); overiiow and local vent pipes (13) (llt) and (l5) communicating with the water closet, wash bowl, and bath tub; a Waste pipe having traps provided with ball valves; vent pipes com municating with said traps and with the soil pipe, substantially as described.

3. In sanitary plumbing, a soil or sewer point where said pipe enters the premises; a Water gage on said soil or sewer pipe at a y point above the fixtures, in combination with trapped waste pipes; vent pipes for said traps communicating with said soil or sewer pipe; ball valves in said traps; safety waste and localvent pipes communicating with the water closet, wash bowl, bath tub, and kitchen sink; a vent pipe communicating with said safety waste pipe, and with said Warm air flue, substantially as described.

In testimony whereof I have hereunto set my hand this 11th day 0f February, 1895.

MICHAEL J. GIBBONS. Vlitnesses:
